(54) Wireless communication terminal with an opening /closing sensing function using a plurality of magnetic pole sensors and method therefor


(57) A wireless communication terminal with an opening/closing function using a plurality of magnetic pole sensors and method therefor is provided. The invention activates or inactivates a display unit via a switch by sensing an opening/closing of a sub-body using the magnetic pole sensors, to thereby prevent a malfunctioning due to a magnetic pole caused by an external magnetic pole generator. The inventive wireless communication terminal comprises a first magnetic pole generator for generating a north (N) magnetic pole, a second magnetic pole generator for generating a south (S) magnetic pole, a first magnetic pole sensor for sensing the N magnetic pole from the first magnetic pole generator, a second magnetic pole sensor for sensing the S magnetic pole from the second magnetic pole generator, a controller for controlling an operation of a switch to activate or inactivate an output unit based on the sense result from the first and the second magnetic pole sensors, the switch performing a switching operation in response to a control signal from the controller, and the output unit activated or inactivated in accordance with the switching operation of the switch.
